Hello, I am here on behalf of my sister. She reduced her thyroid hormone replacement (Levothyroxine) on advice of her endo from 175mcg to 50mcg due to symptoms of sweats although she only really gets this when she exerts herself. She thinks it is a hyperthyroid symptom. She is also really tired, can't concentrate, coming down with viruses and colds, joints are aching, flaky skin all over her face. FT3 repeatedly low or below range. Advice welcome.

(DEC 2017 - 50mcg Levothyroxine)

TSH 6.5 (0.2 - 4.2)

FT4 14.6 (12 - 22)

FT3 3.1 (3.1 - 6.8)

another useless medic. we are seeing too many of these problems on here. Sparklee your sister's T3 is way too low and she needs an increase in meds and a retest after 6 weeks. Has your sister had any blood tests for antibodies, Vitamins B12, D, iron, ferritin and folate. What does her GP think, is he quite happy to let the endo play about with your sister's health. Sack the endo and once your sister has some bloods results post them on here for advice on supplements etc. Meantime check out Seaside Susie, a mine of info about vitamins and supplementation. If your sister has antibodies I would recommend she goes gluten free.

Well no doubt your sis has Hashimoto's and most docs and endos think it isn't a problem. Well it most certainly is and probably explains the sweats! Her TSH needs to be below one to help stop the antibodies and also she deffo needs to go gluten free and possibly even lactofree. Her guts are likely "leaky" due to antibodies and her vitamin levels will be trashed. I will be very surprised if her Vit B12 and Vit D levels aren't way too low.

If she can afford to pay for private finger prick blood tests she should try Blue Horizon or Medichecks (they have offers on a Thursday) they will do all thyroid levels, and B12, Vit D iron, ferritin and folate. The results are back by email within the week. I have been doing my own tests twice per year for the last 4 years. I like to be in control of my own health!! plenty of people on here will interpret the results for you.
